DAVOS, Switzerland (AP) — President Donald Trump on Thursday inaugurated his Board of Peace to lead efforts at maintaining a ceasefire in Israel’s war with Hamas, insisting that “everyone wants to be a part” of the body that could eventually rival the United Nations — despite many U.S. allies opting not to participate.

In a speech at the World Economic Forum, Trump sought to create momentum for a project to map out a future of the war-torn Gaza Strip that has been overshadowed this week, first by his threats to seize Greenland, then by a dramatic retreat from that push.

“This isn’t the United States, this is for the world,” he said, adding, “I think we can spread it out to other things as we succeed in Gaza.”

The event featured Ali Shaath, the head of a new, future technocratic government in Gaza, announcing that the Rafah border crossing will open in both directions next week. That’s after Israel said in early December it would open the crossing, which runs between Gaza and Egypt, but has yet to do so.

The new peace board was initially envisioned as a small group of world leaders overseeing the ceasefire, but it has morphed into something far more ambitious — and skepticism about its membership and mandate has led some countries usually closest to Washington to take a pass.
